Pythagoras' theorem is a fundamental principle in geometry that relates the lengths of the sides in a right-angled triangle. It states that the square of the hypotenuse (longest side) is equal to the sum of squares of the other two sides. This theorem is widely used in mathematics and has practical applications in various fields.
Key points:
- The theorem is expressed as a²+b²=c², where c is the hypotenuse
- It applies specifically to right-angled triangles
- The theorem can be used to find unknown side lengths or verify if a triangle is right-angled
- Various letter combinations may be used to represent the sides in problems
